Single SIM. Read the post before knocking. The front camera is broken. I can bring one from China for 600 Taka if you wait 15-20 days. The display has been replaced. When the phone heats up, the display flickers slightly, but it is very minor and does not cause problems using the phone. (It is not that much, you can barely notice it). Must come to Gulshan-1, Jatrabari, or Narayanganj Signboard.
